PRODUCTS OVERVIEW

SPARK ultra-wideband products solve the problems of power, data rate, latency, and link robustness that limit existing short-range narrowband wireless solutions.

Wireless Transceivers

The SPARK SR1000 UWB IC family takes full advantage of ultra-wideband (UWB) technology to simultaneously deliver industry-leading energy efficiency, latency and bandwidth:

  • Data rates of up to 10 Mbps @ 1.5 nJ/bit energy efficiency
  • 2 mW power consumption while transmitting and receiving 1 Mbps, scaling to 6 uW at 1 kbps
  • Ultra-short wireless latency (50 µs for 1 kb)
  • Time-of-flight positioning at 30 cm accuracy

The SPARK SR1000 family consists of two products:

  • SR1010: 3.1 – 6 GHz Band
  • SR1020: 6 – 9.25 GHz Band

Software Development Kits

PRODUCT

SDK

The SDK is an extensive software suite for the SR1000 Series UWB transceivers. It can be used to simplify and accelerate development for applications such as establishing communication links between two transceivers for low latency, low power data exchange and time-of-flight ranging.

Hardware Kits

PRODUCT

EVALUATION KITS

The SPARK SR1000 Series Evaluation Kit is meant to demonstrate the capabilities of the SR1010 and SR1020 low power, high data rate radio transceiver family. It allows users to benchmark the SR1000 family’s unique qualities in terms of data rate, power consumption, and latency according to different configurable presets.

5 ms LOW LATENCY UNCOMPRESSED AUDIO HEADSET DEMONSTRATOR

The SPARK Headset audio solution is a complete hardware/software solution built to provide a reliable, low latency and uncompressed high quality audio link. The solution uses the SR1020 ultra-low latency high data-rate wireless transceiver, a MAXIM MAX98091 low power stereo codec, and an ARM Cortex-M4 based STM MCU running SPARK’s proprietary audio and wireless software stack.

Specifications include:

  • Configurable sampling rate: 24 kHz and 48 kHz
  • Configurable latency: 3 ms, 5 ms, 10 ms and 20 ms
  • Raw uncompressed 16-bit audio (no compression, no masking)
